Across TCGA pan-cancer cohorts, H2AC1 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of H2AC1’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where H2AC1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types H2AC1 is over-expressed in tumor, although a few such as KICH show the opposite, repressed pattern.
KIRC, KICH, and LIHC are the cancer types where H2AC1 tumor–normal differential expression is most reproducible.
